What is it?
We grow marine microalgae on land using seawater blends, recycled containers, and low-impact materials. These “mini oceans” are small, controlled systems designed to remove carbon dioxide through photosynthesis — the same natural process that occurs in the sea.
Phytoplankton and algae already absorb around half of the carbon dioxide we emit globally. The challenge is that the ocean is absorbing more carbon than it should, contributing to ocean acidification and placing pressure on shell-forming organisms, plankton communities, and wider marine ecosystems.
We are not trying to replace large-scale climate solutions. We are not claiming to solve the climate crisis. What we are creating is a tangible, measurable way for people to take part in carbon removal while learning about ocean chemistry and marine conservation.
Our work focuses on:
- Growing Nannochloropsis marine algae in contained systems
- Exploring enhanced weathering and buffering using locally sourced serpentine rock
- Harvesting and stabilising algal biomass using low-impact methods
- Converting captured carbon into stable forms such as biochar or mineral-bound materials, helping it remain locked away for hundreds of years
Our goal is to remove one tonne of CO2 every year once fully operational.
Every design decision passes through a simple filter:
- Is it food safe and non-hazardous?
- Is it low impact?
- Is it recycled or responsibly sourced?
- Does this increase our carbon footprint, and can we realistically offset that?
Where possible, we use reclaimed containers, recycled plastics, locally sourced rock from Cornwall and nutrient blends that are compost safe and seawater compatible.
This is not just a science project. It is a community climate project. We run workshops, open days and volunteering opportunities so people can understand what ocean acidification actually means, how carbon moves through natural systems and what practical action looks like at human scale.
The aim is to build a small but replicable model. Something that could work in other communities, and one day could sit in gardens, schools or community spaces. We want this to be something honest, measurable and, above all, something hopeful.
If that approach resonates with you, we would be glad to welcome you.
